Abstract

The utilization of vegetable oils modification as a renewable raw material has attracted many researchers. In particular, epoxidized fatty acid methyl ester derived from plant oils such as palm oil can be used as stabilizers and plasticisers in polymer, as lubricant additives and as intermediate product for synthesis of polyurethane foam. Palm oil methyl ester (POME) is a potential raw material for synthesis of epoxidized palm oil methyl ester (EPOME) as palm oil contains high amount of unsaturated fatty acid and excess amount of palm oil production in Indonesia. Palm oil is converted to palm oil methyl ester and then followed by epoxidation reaction to produce EPOME. A response surface methodology was utilized to determine the influence of molar ratio of POME/H2O2 and reaction time on reaction conversion and oxirane content. In addition, the optimal operating conditions are determined and indicated by high oxirane content. The epoxidation reaction was performed in a batch reactor using acetic acid as an oxygen carrier. A central composite design, with two independent variables and two response functions was performed to determine the influence of the input variables. The conversion of reaction increased with increasing reaction time and molar ratio of POME/H2O2. The optimal operating condition indicated by maximum oxirane value was achieved with a reaction time of 4.13 hours and at a molar ratio POME/H2O2 of 1:1.83.
